While you're at it, you might want to: * If you're running a 64-bit OS, upgrade to a 64-bit JVM. ~ Without this, your 6GB -> 8GB memory upgrade isn't going ~ to give your Java process any more memory, since the 32-bit ~ JVMs can only give you about 2GB of useful heap. * Consider running fewer application per JVM.

This is not surprising. Java uses a lot of String objects internally for lots of stuff (like package, class, and method names, for instance) and every single one of them is backed by a character array. Don't read too much into the fact that character arrays take up a lot of space, because they can be allocated in all kinds of ways that are not related to the "character array" itself. What you really want to do is run a profiler to find out where many of the character arrays were created in the first place. Good luck, - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkeogdsACgkQ9CaO5/Lv0PBATwCfaOcnTrgBCr/Dfm8e/R+/1xpk fRUAnRL+Pe4mRmUSBsK3Ts+JPGZ3o9N8 =CkWb -----END PGP SIGNATURE----- --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
